[112.21] CH 3 GHz Observations of the Galactic Center

We present the most sensitive observations to date of the CH
3335 MHz line in the direction of the Galactic Center. A 3 x
3 map of the region was made at 9' resolution (21 pc at the
distance of the Galactic Center) showing a velocity extent
for the CH emission similar to that seen with the CO(1-0)
transition. A narrow CH component at about 0 km/s present in
all the CH spectra is most likely produced by molecular
clouds in the Inner Galaxy and can be used to calculate the
scale height of these objects (90 - 240 pc). This estimate
is significantly larger than that for GMCs in the disk and
possibly indicates a low-intensity, thick molecular disk
component.
